Abstract: L'invention concerne un codeur audio appliquant un processus de codage par bloc adaptatif à des segments d'informations audio, afin de générer des trames d'informations codées alignées par rapport à un signal de référence qui transmet l'alignement d'une suite de trames d'informations vidéo. Les informations audio sont analysées de manière à déterminer diverses caractéristiques dudit signal audio, par exemple la présence et l'emplacement d'une transitoire, un signal de commande étant généré de sorte que ledit processus de codage par bloc adaptatif code des segments de longueur variable. Un décodeur complémentaire applique par ailleurs un processus de décodage par bloc adaptatif permettant de récupérer les segments d'informations audio à partir des trames d'informations codées. Dans certains modes de réalisation utilisant des transformées TDCA (suppression du repliement dans le domaine temporel), des fonctions fenêtres et des transformées sont appliquées selon un modèle de segment définissant des fonctions fenêtres et des paramètres de transformées pour chaque segment d'une suite de segments. De plus, les segments de chaque trame d'une suite de trames se recouvrant peuvent être extraits sans artefacts de repliement, et ce indépendamment de la récupération de segments d'autres trames. Enfin, les fonctions fenêtres sont conçues pour fournir des réponses dans le domaine fréquentiel préférées et des profils de gain dans le domaine temporel préférés.

Abstract: A method and apparatus are disclosed for filtering an input wavelength division multiplexed (WDM) signal comprised of N wavelength channels. The disclosed wavelength blocker includes a demultiplexer for producing a plurality of demultiplexed output signals from the input WDM signal and a multiplexer for producing an output WDM signal. In addition, a shutter array selectively passes each of the N  wavelength channels using a plurality of shutters. The demultiplexer is coupled to the multiplexer using a plurality of waveguides having approximately equal length, in order to reduce multipath interference. The shutters may be embodied, for example, as Mach-Zehnder switches, electro-absorption modulators or Y-branch switches. Each of the N wavelength channels in the incoming signal are selectively passed or blocked using a thermo-optic or electro-optic control signal to control the state of the corresponding shutter. Crosstalk among the various N channels can be reduced using dilation techniques that position two shutters in series, especially where the shutters are thermo-optic Mach-Zehnder switches. Wavelength-selective cross connects and wavelength add-drop multiplexers are also disclosed that employ the novel wavelength blockers.

Patent CA-2388913-C (CA)
Title: Cleaning system utilizing an organic cleaning solvent and a pressurized fluid solvent
Inventor: SCHULTE JAMES E
IPC: C11D7/26
Filed: 2000-10-13
Granted: 2004-04-13
Abstract: A cleaning system that utilizes an organic cleaning solvent and pressurized fluid solvent is disclosed. The system has no conventional evaporative hot air drying cycle. Instead, the system utilizes the solubility of the organic solvent in pressurized fluid solvent as well as the physical properties of pressurized fluid solvent.  After an organic solvent cleaning cycle, the solvent is extracted from the textiles at high speed in a rotating drum in the same way conventional solvents are extracted from textiles in conventional evaporative hot air dry cleaning machines. Instead of proceeding to a conventional drying cycle, the extracted textiles are then immersed in pressurized fluid solvent to extract the residual organic solvent from the textiles. This is possible because the organic solvent is soluble in pressurized fluid solvent. After the textiles are immersed in pressurized fluid solvent, pressurized fluid solvent is pumped from the drum. Finally, the drum is de-pressurized to atmospheric pressure to evaporate any remaining pressurized fluid solvent, yielding clean, solvent free textiles. The organic solvent is preferably dipropylene glycol n-butyl ether, tripropylene glycol n-butyl ether or tripropylene glycol methyl ether, a mixture thereof, or a similar solvent and the pressurized fluid solvent is preferably densified carbon dioxide.

Title: Silicon nanoparticle microcrystal nonlinear optical devices
Inventor: NAYFEH MUNIR H
IPC: H01S5/10
Filed: 2001-05-17
Granted: 2007-07-31
Abstract: Harmonic incident radiation is obtained from a silicon nanoparticle microcrystal (10) or microcrystal film. The silicon nanoparticle microcrystals are formed from silicon nanoparticles of about 1 nm and having about 1 part per thousand or less larger than 1 nm. The preferred film comprises silicon nanoparticles, dimensioned on the order of one nanometer, reconstituted into a device quality crystalline film. The microcrystal film emits the second harmonic of incident radiation for excitation in the range of about 600 -- 1000nm. A preferred device according to the invention includes a silicon nanoparticle microcrystal film formed on a substrate, such as silicon or glass. Crystals of the silicon nanoparticles, due to the harmonic response, also demonstrate the capability to serve as piezoelectric material and as an improved biological marker. Since the emission response of the silicon nanoparticle crystals will be influenced by surrounding electric fields, the microcrystals also provides for electrochromatic mapping of electric field distribution in general and in electronic devices.

IPC: E01B27/16
Filed: 2003-04-11
Granted: 2010-08-31
Abstract: A conversion device that is structured to be coupled to the rotating axle of a motor and to an output assembly. The output assembly has an elongated shaft with an axis extending generally perpendicular to the axis of the motor axle. The output assembly further is coupled to a frame to resist movement in an axial direction. The conversion device includes an eccentric hub having a disk with a sidewall extending from the perimeter thereby forming a recess and a yoke having a shaft and an attachment pin. The disk is coupled to the motor axle. The yoke shaft is disposed within the eccentric hub recess and the attachment pin is pivotally coupled to the output assembly. As the eccentric hub is rotated by the motor, the hub causes the yoke moves in a circular path. The circular path of the yoke has directional components that are parallel to the axis of the output assembly shaft and perpendicular to the axis of the output assembly shaft. The attachment pin allows the yoke to pivot in a direction parallel to the axis of the output assembly shaft. Thus, only the motion perpendicular to the axis of the output assembly shaft is transferred to the output assembly shaft. This motion is a reciprocal rotational motion about the axis of the output assembly shaft.
